01 - Preheat oven to 375°F. Line a 12-cup muffin tin with paper liners or lightly grease each cup.
02 - In a large bowl, whisk together flour, sugar, baking powder, baking soda, and salt until evenly mixed.
03 - In a separate bowl, beat eggs, milk, vegetable oil, and vanilla extract until smooth and fully incorporated.
04 - Pour the wet mixture into the dry ingredients. Stir gently just until combined; a few lumps remaining is acceptable to maintain moisture.
05 - Fold in most of the chocolate chips, reserving a small portion for topping the muffins.
06 - Divide batter evenly into muffin cups, filling each about three quarters full. Sprinkle reserved chocolate chips on top.
07 - Bake for 18 to 20 minutes, or until a toothpick inserted into the center comes out clean or with a few moist crumbs.
08 - Allow muffins to cool in the pan for 5 minutes before transferring to a wire rack to cool completely.
